Anyone else enjoy just browsing patents for fun? I think its awesome to see the thought process behind markers/inventions and possibly find sneak peeks at things.

Some of the coolest I've found were everything Simon does, early Planet Eclipse markers, DYE markers, of course the Splat master and 007 (and clones) as well as accessories like the POPS ASA and efficiency modifications

I know that Doc's Machine/others have been doing X-rays for decorations. Sort of inspired me:
I'm thinking about taking patent drawings like this POPS ASA
